Meet Our Team


Becky Harsh (CF-L4)


I love coaching and I’m very excited to be coaching at CrossFit Castle Rock. Castle Rock is my home and has been for the last 18 years. My husband and I have been married for almost 26 years and we have two “adult” boys. I found CrossFit in October 2006 and to be honest, at that point the direction of my life changed. Almost immediately I began coaching CrossFit. For the last decade I’ve been working for CrossFit HQ on the Seminar Staff and more recently I began working for the CrossFit Games team as the Athlete Communications Manager. I can’t wait to see you all at the gym!
